Medicaid Dental Benefits for Pregnant People and Dental Care Use Among Very Young Children.

OBJECTIVES: The aim of this study was to examine the association between Medicaid dental benefits for pregnant people and dental care use among very young children in Medicaid. We hypothesized that children living in states with more generous dental benefits for Medicaid-enrolled pregnant people would be more likely to have a recent dental visit. METHODS: This national cross-sectional study used pooled 2017-2019 data from the National Survey of Children's Health, as well as state Medicaid policy data. The study sample included children aged 0-2 enrolled in Medicaid. Multivariable logistic regression models estimated the association between Medicaid dental benefit generosity for pregnant people and the child having a dental visit in the past year. RESULTS: Children in states with emergency-only dental coverage for pregnant people were 2.5 times as likely to have had a dental visit than children in states with extensive coverage (OR 2.48, 95% CI 1.35-4.53). In supplemental analyses excluding children living in Texas, there was no longer an association between dental coverage for pregnant people and dental utilization among young children (OR 1.52, 95% CI 0.82-2.83). CONCLUSIONS FOR PRACTICE: Young children in states that provided emergency-only dental benefits for pregnant people in Medicaid had significantly higher odds of dental utilization than young children in states with more generous dental benefits for pregnant people. This relationship disappeared after excluding the state Texas, which had the highest rate of child dental utilization in the country and provided emergency-only dental benefits for pregnant people in Medicaid.

Perceived social status, socioeconomic status, and preventive dental utilization among a low-income Medicaid adult population.

OBJECTIVES: Perceived Social Status (PSS) is a measure of cumulative socioeconomic circumstances that takes perceived self-control into account. It is hypothesized to better capture social class compared to socioeconomic status (SES) measures (i.e., education, occupation, and income). This study examined the association between PSS and dental utilization, comparing the strength of associations between dental utilization and PSS and SES measures among a low-income adult Medicaid population. METHODS: A cross-sectional survey was administered to a random sample of low-income adults in Iowa, United States with Medicaid dental insurance (N = 18,000) in the spring of 2018. Respondents were asked about PSS, dental utilization, and demographics. A set of multivariable logistic regression models examined the relative effects of PSS and SES measures on dental utilization, controlling for age, sex, health literacy, whether the respondent was aware they had dental insurance, transportation, and perceived need of dental care. RESULTS: The adjusted response rate was 25%, with a final sample size of 2252. Mean PSS (range 1-10) was 5.3 (SD 1.9). PSS was significantly associated with dental utilization (OR = 1.11; CI = 1.05, 1.18) when adjusting for control variables, whereas other SES measures-education, employment, and income-were not. CONCLUSIONS: PSS demonstrated a small positive association with dental utilization. Results support the relative importance of PSS, in addition to SES measures, as PSS may capture aspects of social class that SES measures do not. Results suggest the need for future research to consider the effects of PSS on oral health outcomes and behaviors.

Dentist-reported differences in services provided to patients with public vs. private dental insurance.

INTRODUCTION: Variation in dentists' provision of types of dental services based on patients' insurance may impact population access to comprehensive care. The aim of this study was to describe differences in the types of services provided to adult patients with Medicaid versus private insurance among private practice general dentists. METHODS: The data source was a 2019 survey of private practice dentists in Iowa, and the study sample included general dentists with current or recent participation in Iowa's Medicaid program for adults (n = 264). Bivariate analyses were used to compare differences in the types of services provided to privately insured and publicly insured patients. RESULTS: Dentists reported the greatest differences in services provided to patients with public versus private insurance for prosthodontic procedures, including complete dentures, removable partial dentures, and crown and bridge services. Endodontic services were the least frequently provided category of services provided by dentists for both patient groups. Patterns were generally similar among both urban and rural providers. CONCLUSION: Access to dental care for Medicaid members should be evaluated not only on the proportion of dentists who see new Medicaid patients but also on the types of services dentists provide to this population.

Association of Medicaid expansion with dental emergency department visits overall and by states' Medicaid dental benefits provision.

BACKGROUND: Evidence on the association of Medicaid expansion with dental emergency department (ED) utilization is limited, while even less is known on policy-related changes in dental ED visits by Medicaid programs' dental benefits generosity. The objective of this study was to estimate the association of Medicaid expansion with changes in dental ED visits overall and by states' benefits generosity. METHODS: We used the Healthcare Cost and Utilization Project's Fast Stats Database from 2010 to 2015 for non-elderly adults (19 to 64 years of age) across 23 States, 11 of which expanded Medicaid in January 2014 while 12 did not. Difference-in-differences regression models were used to estimate changes in dental-related ED visits overall and further stratified by states' dental benefit coverage in Medicaid between expansion and non-expansion States. RESULTS: After 2014, dental ED visits declined by 10.9 [95% confidence intervals (CI): -18.5 to -3.4] visits per 100,000 population quarterly in states that expanded Medicaid compared to non-expansion states. However, the overall decline was concentrated in Medicaid expansion states with dental benefits. In particular, among expansion states, dental ED visits per 100,000 population declined by 11.4 visits (95% CI: -17.9 to -4.9) quarterly in states with dental benefits in Medicaid compared to states with emergency-only or no dental benefits. Significant differences between non-expansion states by Medicaid's dental benefits generosity were not observed [6.3 visits (95% CI: -22.3 to 34.9)]. CONCLUSIONS: Our findings suggest the need to strengthen public health insurance programs with more generous dental benefits to curtail costly dental ED visits.

Dentist attitudes toward an annual benefit maximum in Iowa's adult Medicaid program.

OBJECTIVES: The Dental Wellness Plan (DWP) provides dental coverage for adult Medicaid enrollees in Iowa. In September 2018, a $1000 annual benefit maximum (ABM) was implemented in the DWP program. The aim of this study was to explore private dentists' attitudes toward ABMs and factors associated with ABM attitudes. METHODS: The data source was a mailed survey administered in spring 2019 to all private practice dentists in Iowa. The two dependent variables were (1) attitude toward the $1000 ABM and (2) attitude toward any ABM generally. Independent variables included demographic and practice-related factors, and participation in and attitudes toward the DWP. Descriptive, bivariate, and multivariable analyses were conducted. RESULTS: While over half (56%) of providers reported a positive attitude toward "Any ABM," less than half (40%) reported a positive attitude toward the "$1000 ABM." Attitudes toward both "$1000 ABM" and "Any ABM" were significantly and positively associated with attitudes toward DWP overall and toward DWP structure. Independent variables that were significantly associated with both the "$1000 ABM" and "Any ABM" included overall attitude toward the DWP, attitude toward DWP structure, and practice busyness. CONCLUSIONS: Utilizing an ABM, particularly one set at $1000 for a Medicaid program, elicits mixed attitudes among dentists. Future research should evaluate the impact of Medicaid ABMs on long term dentist participation and patient's ability to receive needed care.

Randomized experiment on the effect of incentives and mailing strategy on response rates in a mail survey of dentists.

OBJECTIVES: Response rates for mail surveys of dentists and other health care providers have declined appreciably over the past several decades. The objective of this study was to update evidence about the impact use of incentives and different mail strategies on response rates in a mail survey of dentists. METHODS: We randomized private practice dentists in Iowa (N = 1267) into six study groups to test the effects of incentives and mail strategy on response rate. Survey incentives included either a $2 bill or a customized pen/stylus; a control group with no incentive was included. Mail strategies included bulk mail or first-class stamps. RESULTS: The overall survey response rate was 43%. A $2 bill incentive was associated with significantly higher likelihood of returning a survey compared to the control group with no incentive (48% response rate vs. 40%, respectively). A non-monetary incentive was not significantly associated with likelihood of response. Use of first-class stamps compared to bulk mail did not significantly affect response rate. CONCLUSIONS: This study demonstrated the effectiveness of a $2 incentive to increase response rate in a mail survey of dentists. Given the background trend of declining survey participation rates, researchers should consider use of monetary incentives and explore new strategies to increase participation among dentists and other health care providers.

Food Insecurity Is Prevalent in Iowa's Medicaid Expansion Population.

BACKGROUND: Food insecurity has been identified as an important social determinant of health and is associated with many health issues prevalent in Medicaid members. Despite this, little research has been done around food insecurity within Medicaid populations. OBJECTIVE: Our objective was to estimate the prevalence of household food insecurity and identify factors associated with experiencing food insecurity in Iowa's Medicaid expansion population. DESIGN: We conducted a cross-sectional telephone survey between March and May of 2019. PARTICIPANTS: Our sample was drawn from Medicaid members enrolled in Iowa's expansion program at least 14 months, stratified by Federal Poverty Level (FPL) category. Members who did not have valid contact information were excluded. We selected one individual per household to reduce the interrelatedness of responses. We sampled 6,000 individuals and had 1,349 respondents in the analytic sample. MAIN OUTCOME MEASURE: Our main outcome was whether a respondent's household experienced food insecurity in the previous year, using the Hunger Vital Sign screening tool. STATISTICAL ANALYSES PERFORMED: We weighted responses to account for the sampling design and differential nonresponse between strata. We estimated the prevalence of food insecurity and used logistic regression to model food insecurity as a function of demographic (age, FPL category, gender, employment, education, race, rurality, and Supplemental Nutrition Assistance Program [SNAP] participation) and health-related (self-rated health, self-rated oral health, health literacy) factors. RESULTS: The estimated prevalence of experiencing food insecurity was 51.3%. Race, gender, education, employment, health literacy, and self-rated health were all significantly associated with food insecurity. CONCLUSIONS: Our findings show that food insecurity is prevalent in Iowa's Medicaid expansion population. Food insecurity should be more widely measured as a critical social determinant of health in Medicaid populations. Policymakers and clinicians should consider interventions that connect households experiencing food insecurity to food resources (eg, produce prescriptions and food pantry referrals) and policies that increase food access. ABBREVIATIONS: Iowa Wellness Plan (IWP); Federal Poverty Level (FPL); Healthy Behavior Program (HBP); Supplemental Nutrition Assistance Program (SNAP).

Patient centered dental home: Building a framework for dental quality measurement and improvement.

INTRODUCTION: This article presents results of the second phase of a project to develop a patient-centered dental home (PCDH) model. Aims of PCDH model development include broadening the scope of prior dental home definitions to include populations across the lifespan, developing a quality measurement framework to facilitate quality assessment and improvement, and promoting opportunities for medical-dental integration through alignment with existing PCMH models. This phase determined the components, or conceptual subdivisions, associated with a previously developed PCDH definition and characteristics. METHODS: We used a modified Delphi process to obtain structured feedback and gain consensus among the project national advisory committee (NAC). The process included a web-based survey that asked NAC members to rank the importance of each potential component on a scale of 1-9. Criteria for consensus on component inclusion/exclusion combined a median rating and measure of disagreement. Respondents were also encouraged to provide open-ended feedback regarding rationale for component ratings and additional suggested components. RESULTS: A total of 47 out of 51 members completed the survey. All 34 components met the quantitative criteria for inclusion in the PCDH model. Changes were made to components based on open-ended feedback. CONCLUSIONS: This project phase further developed a PCDH measurement framework that aims to guide practice transformation, quality measurement and improvement in dental care delivery, as well as integration between medicine and dentistry. Using a Delphi approach with a broad group of stakeholders ensured that components had face validity and were conceptually aligned with the PCDH definition and characteristics.

Applying "Stages of Readiness to Change" Model to Dentists' Decisions to Participate in Medicaid: An Exploratory Study.

BACKGROUND: The Stages of Readiness to Change (SOC) behavioral model describes behavior change as a process and distinguishes individuals based on their current behavior and readiness to change that behavior. SOC can be used to improve dentists' participation in a state public dental benefit program (Medicaid) by targeting them at different SOC with interventions, strategies, and tools tailored to those stages. Therefore, this study assessed the usefulness of using SOC to describe dentists' attitudes towards and participation in Medicaid. Dentists' participation in Medicaid is of interest to policymakers, and this study demonstrates a method to identify potential opportunities for intervention. METHODS: A modified SOC algorithm used data from a periodic survey of Iowa Dentists to categorize dentists (N=514) into: 1) pre-contemplation, 2) considering participation (SOC contemplation and preparation), 3) acting (SOC action and maintenance), and 4) risk of relapse (at risk for discontinuing participation). The four SOC stages were compared using ANOVA and post hoc Tukey's test among: practice characteristics, Dentists Altruism scale, Attitude about Program Administration scale, Attitude about Medicaid patients scale and Perception of Importance of Medicaid Problems scale. RESULTS: Among survey respondents, 36% were categorized as pre-contemplation, 6% were considering Medicaid participation, 12% were acting as Medicaid providers with minimal risk of relapse, and 46% were participating and at risk of discontinuing. Dentists' attitudes towards program administration, Medicaid patients, and access to care varied across the SOC cycle. CONCLUSION: Nearly, 46% dentists in this analysis were identified as at risk of discontinuing participation - a much larger proportion than dentists considering Medicaid participation. Categorizing dentists using this approach has important implications for programmatic interventions. For example, policymakers targeting our study population could focus their efforts on reducing the likelihood of dentists dropping out of the program, with less emphasis targeting dentists in the precontemplation stage.

Dental Care in Programs of All-Inclusive Care for the Elderly: Organizational Structures and Protocols.

OBJECTIVES: This study uses a national model of community-based long-term services and supports, the Program of All-inclusive Care for the Elderly (PACE), to identify organizational structures and protocols that can facilitate the delivery of dental examinations. DESIGN: We developed an online survey instrument and conceptual model for this study representing 10 domains believed to characterize a quality PACE dental program. SETTING AND PARTICIPANTS: The Qualtrics survey was distributed nationally to all 124 PACE programs in the 31 states PACE was available. Respondents in this study represented 35 programs (program response rate = 28.2%) in 23 states (state response rate = 74.2%). METHODS: Selected independent variables from each of the 10 domains were tested against the reported delivery of dental examinations variable using the Kendall τ and χ2. Twenty-nine programs were included in the final analysis. RESULTS: Most programs mandated a dental examination within 31-60 days of enrollment (63.6%). Few programs had a dental manual (15.6%) or any quality assurance for dental care (32.3%). A majority of programs (58.8%) stated that they had a protocol for enrollees to receive a cleaning every 6-12 months. Having a system for quality assurance for dental care, protocol for a cleaning every 6-12 months, mandating a comprehensive dental examination and providing preventive dental services onsite with built-in equipment, were all statistically associated with a higher reported delivery of dental examinations. CONCLUSION AND IMPLICATIONS: Organizations providing long-term services and supports, including PACE, can use these identified domains to develop minimal standards to ensure dental care is part of innovative models of community-based long-term services and supports. Implementing these domains can facilitate effective delivery of dental examinations that have the potential to support positive oral health and general health outcomes.

Communicating a Complicated Medicaid Waiver Program to Enrollees in Iowa: How Federally Qualified Health Centers Support Medicaid Members.

Iowa expanded Medicaid eligibility with a waiver including a personal responsibility component. Early program evaluation revealed low compliance and awareness among members. There is little research on leveraging existing contact points in the health care system to effectively communicate with Medicaid enrollees. We interviewed outreach and enrollment staff at Federally Qualified Health Centers (FQHCs) to explore their work. We show that FQHCs use several strategies to enroll individuals in appropriate programs and support them in understanding and navigating their health insurance coverage. With increasingly complex Medicaid programs, this support will be more widely needed to prevent hardship and loss of coverage.

Implementation Matters: Lessons From Iowa Medicaid's Healthy Behaviors Program.

Iowa's Medicaid expansion includes the Healthy Behaviors Program (HBP), which incentivizes enrollees to receive a wellness exam and complete a health risk assessment annually to waive a monthly premium. We conducted a telephone survey with enrollees to examine their awareness and understanding of the HBP, and we then merged the survey data with claims data to examine factors associated with the completion of program requirements. As found in previous research, awareness of the HBP remains low, with approximately half of respondents unaware of the program or the premium requirement. Our results suggest that four years after the program was implemented, requirements are not being effectively communicated to enrollees. When designing and implementing such programs, policy makers should note that they are unlikely to succeed without consideration of how the program is structured and promoted. Limited program awareness is likely to result in low participation and consequences related to paying premiums or being disenrolled.

Iowa's Medicaid Healthy Behaviors Program Associated With Reduced Hospital-Based Care But Higher Spending, 2012-17.

Health behavior incentive programs are increasingly common in Medicaid programs nationwide. Iowa's Healthy Behaviors Program (HBP) requires Medicaid expansion enrollees to complete an annual wellness exam and health risk assessment or pay monthly premiums to avoid disenrollment. The extent to which the program reduces the use of hospital-based care and lowers health care spending is unknown. Using data for 2012-17 from Medicaid and for 2014-17 from HBP, we evaluated changes in use and spending associated with HBP participation. Compared to nonparticipants, HBP participants were less likely to have an emergency department visit or be hospitalized (by 9.6 percentage points and 2.8 percentage points, respectively) but had higher total health care spending ($1,594). Meanwhile, Iowa's Medicaid expansion was associated with increased use and spending independent of HBP participation-that is, applying to both participants and nonparticipants. Overall, our findings suggest that the HBP was associated with substantial reductions in hospital-based care but increased health care spending.

Setting the PACE for frail older adults in the community: An underused opportunity for furthering medical-dental integration.

BACKGROUND: The integration of dentistry into comprehensive and long-term care has occurred infrequently and with limited success. The authors aim to describe how the Program of All-Inclusive Care for the Elderly (PACE) has the potential for such incorporation for the growing population of nursing home-appropriate older adults preferring to age in place. METHODS: The authors used a 56-item online survey to explore aspects of oral health care within PACE, including organizational structure, availability and provision of care, preventive protocols, and provider reimbursement. The survey was distributed to all 124 programs nationally. Data analyses included descriptive statistics for each of the variables of interest. RESULTS: Thirty-five programs completed the survey (28%) in 23 states (74%) where PACE is available. Most programs covered comprehensive dental services and predominantly provided care off-site. Most programs reimbursed dentists at Medicaid fee-for-service rates and some at commercial rates. Dentistry was most frequently ranked the second-highest specialty focus behind mental health. CONCLUSIONS: PACE is a comprehensive interdisciplinary model of care and an underused opportunity for furthering medical-dental integration. It uses local dental resources in order to accommodate the oral health care needs of the growing population of older adults preferring to age in place. PRACTICAL IMPLICATIONS: PACE is an opportunity for the dental profession to further medical-dental integration and ensure that newer models of long-term care include comprehensive and coordinated oral health care programs. It is also an opportunity to promote an integrated model of care with policy makers to support integrated oral health care for the nursing home-eligible population.

Purged from the Rolls: A Study of Medicaid Disenrollment in Iowa.

Purpose: To describe the impact of disenrollment from Medicaid because of failure to pay premiums as part of Iowa's Medicaid program's personal responsibility component. Methods: We conducted a mixed method study consisting of in-depth interviews with disenrolled members in 2016 and 2017 (n=72) and a survey of disenrolled members in 2017 (n=225). Results: Many disenrollees did not know why they were disenrolled, were unaware of the personal responsibility component or premium requirement, and were confused by the disenrollment process. Disenrollment had negative effects including stress, financial burden, and engaging in behaviors such as skipping medication and postponing medical or dental care. Furthermore, disenrollees were often unable to enroll in health insurance, and for those who did, many reported it was a difficult process. Conclusions: Disenrollment had numerous, negative impacts on members who failed to pay their premiums. There was confusion about program requirements, which might indicate challenges communicating about a complicated program. Policymakers need to consider how to design and implement personal responsibility programs to achieve their desired outcome and reduce confusion and negative consequences.

Member and dentist narratives about a dental programme for the Medicaid expansion population: A content analysis.

OBJECTIVES: In the United States, the 2010 Affordable Care Act's Medicaid expansion improved financial access to dental care for new Medicaid enrollees in states with Medicaid dental benefits for adults. Using an existing theoretical framework, we explored dentist and Medicaid member narratives concerning a state's redesigned dental programme for the Medicaid expansion population. METHODS: Data sources include two surveys conducted in 2016-one to a random sample of Medicaid members and one to private practice dentists in Iowa. A qualitative content analysis approach was used to quantify and describe themes present in open-ended comment data. RESULTS: The most common themes among Medicaid member narratives were related to oral health needs and status, availability of dentists who accept Medicaid, and Medicaid coverage for dental care. Among dentists, the programme's administrative burden was the most common theme, with coverage and reimbursement commonly cited as well. An emergent theme among both member and dentist comments was patient confusion or lack of knowledge about programme enrolment and coverage. CONCLUSIONS: Member awareness about enrolment and coverage in public dental benefit plans should be further explored to determine the impact on access to care. Effectively communicating the intent, programme design and expectations of a Medicaid programme to both providers and Medicaid members is important to the success of the programme.

A tale of two public dental benefit programs: Iowa dentist participation in traditional Medicaid versus a Medicaid expansion program.

BACKGROUND: In Iowa from 2014 to 2017, there were 2 separate public dental benefit programs for Medicaid-enrolled adults: one for the Medicaid expansion population called the Dental Wellness Plan (DWP), and one for the traditional, non-expansion adult Medicaid population. The programs differed with respect to reimbursement, administration, and benefit structure. This study explored differences in patterns and predictors of dentist participation in the two programs. METHODS: Authors sent a survey to all private practice dentists in Iowa (n = 1301) 2 years after DWP implementation. Descriptive, bivariate, and logistic regression analyses were used to examine patterns and predictors of dentist participation in Medicaid and DWP. RESULTS: Overall rates of dentists' acceptance of new Medicaid and DWP patients were 45 and 43%, respectively. However, Medicaid participants were much more likely than DWP participants to place limits on patient acceptance. Adjusting for other factors, practice busyness was the only significant predictor of DWP participation, and practice location was the only significant predictor of Medicaid participation. Dentists who were not busy enough were more than twice as likely to participate in DWP compared to others, and dentists in rural areas were almost twice as likely to participate in Medicaid compared to dentists in urban areas. CONCLUSIONS: Dentist participation in Medicaid is an ongoing concern for states aiming to ensure access to dental care for low-income populations. We found distinct participation patterns and predictors between a traditional Medicaid dental program and the DWP, suggesting different motivations for participation between the two programs.

The patient-centered dental home: A standardized definition for quality assessment, improvement, and integration.

OBJECTIVE: To develop the first standardized definition of the patient-centered dental home (PCDH). DATA SOURCES/STUDY SETTING: Primary data from a 55-member national expert panel and public comments. STUDY DESIGN: We used a modified Delphi process with three rounds of surveys to collect panelists' ratings of PCDH characteristics and open-ended comments. The process was supplemented with a 1-month public comment period. DATA COLLECTION/EXTRACTION METHODS: We calculated median ratings, analyzed consensus using the interpercentile range adjusted for symmetry, and qualitatively evaluated comments. PRINCIPAL FINDINGS: Forty-nine experts (89%) completed three rounds and identified eight essential PCDH characteristics, resulting in the following definition: "The patient-centered dental home is a model of care that is accessible, comprehensive, continuous, coordinated, patient- and family-centered, and focused on quality and safety as an integrated part of a health home for people throughout the life span." CONCLUSIONS: This PCDH definition provides the foundation for developing measures for research, care improvement, and accreditation and is aligned with the patient-centered medical home. Consensus among a broad national expert panel-including provider, payer, and accreditation stakeholder organizations and experts in medicine, dentistry, and quality measurement-supports the definition's usability and its potential to facilitate medical-dental primary care integration.
